A public water supply is a system that provides water to a community for drinking, cooking, and sanitation. This water is typically sourced from rivers, lakes, or underground aquifers and is treated to ensure it meets safety standards. Public water systems are managed by local or regional authorities to ensure reliable access to clean water for residents. These systems are essential for public health, as they help prevent waterborne diseases and support daily activities. Regular testing and maintenance are conducted to monitor water quality and infrastructure. Public water supply systems are often funded through taxes and user fees, ensuring sustainability and accessibility for all.
